Thermal effect in dynamic yielding and fracture of metals and alloys
Thermal effect in dynamic yielding and fracture of metals and alloys
The explanation of transition between ductile and brittle modes of fracture based on the "incubation time" concept is proposed. This approach allows us to establish relation between the influences of different loading parameters (strain-rate, temperature) on the mode of fracture. Proposed criteria give explanation to anomalous behavior of yield limit and possible high-temperature embrittlement.

Abstract
The explanation of transition between ductile and brittle modes of fracture based on the "incubation time" concept is proposed. This approach allows us to establish relation between the influences of different loading parameters (strain-rate, temperature) on the mode of fracture. Proposed criteria give explanation to anomalous behavior of yield limit and possible high-temperature embrittlement.
